Answer:
(2, 6)
Step-by-step explanation:
The x value is not going to be changed, but the y value is going to multiply by 1.5. Therefore, the y value would be 4*1.5 = 6.
The answer is (2,6).
Answer:
infinite number of solutions
Step-by-step explanation:
Work with the second equation. Subtract 8x from both sides.
- 4y + 8x - 8x = -8x - 12 Collect like terms.
-4y = - 8x - 12 Divide by - 4
-4y/-4 = - 8x/-4 - 12/-4
y = 2x + 3
That is exactly the same line as the first given. There is an infinite number of solutions.
1 minute = 60 seconds
1 minute 35 seconds = 60 + 25 = 95 seconds
Speed = 400 meters / 95 seconds
Speed = 4.21 meters / second
Answer:
about 6.87%
Step-by-step explanation:
First, set up your problem:
<u>$13.13</u> = <u>x %</u>
$191 100%
Explaining the setup: $191 is the total, so it is equal to 100%. We're trying to find what percent $13.13 is of $191, so we can call that x %. Then, because they are equal to each other, cross multiply.
You should end up with this:
1313 = 191x
Simplify the equation:
x = 6.874 . . .
Then, round to the given value.
(nearest hundredth) 6.87%
19/20= 0.95
Divide 19 and 20 to get your answer:)
